Spring guiding wheel device and photovoltaic module operation and maintenance robot

Abstract

The invention relates to a spring guiding wheel device. The spring guiding wheel device comprises a guiding wheel support, at least two guiding wheels, at least two U-shaped supports and elastic assemblies, wherein the guiding wheels are rotatably arranged on the guiding wheel support and can enable the guiding wheel support to move; first ends and second ends of the U-shaped supports can rotatably fix the guiding wheels; third ends of the U-shaped supports are connected with the guiding wheel support; after sleeving the third ends of the U-shaped supports, the elastic assemblies are connectedwith the guiding wheel support; and when the elastic assemblies deform, the U-shaped supports drive the guiding wheels to move so as to change the distance between each guiding wheel and the guidingwheel support, and the guiding wheels move vertically. The provided guiding wheel device is simple in structural design and low in cost, and crossing actions of an operation and maintenance robot between photovoltaic modules can be realized quite well.

Description

technical field [0001] The invention relates to a spring guide wheel device, in particular to a guide wheel device that can automatically walk and overcome obstacles on both sides of the transportation track of an operation and maintenance robot between photovoltaic arrays. Background technique [0002] During the operation of the photovoltaic power station, due to the influence of dust and dirt on the surface of the photovoltaic module, the actual light energy received by the photovoltaic module will decrease to a certain extent, which will affect the actual power generation effect of the photovoltaic power station. Therefore, an operation and maintenance robot between photovoltaic arrays was born. However, at present, the arrangement of photovoltaic modules in various photovoltaic power plants is different. Due to the limitation of space and installation requirements, the arrangement of photovoltaic modules is different in density, height and height, and the arrangement of...

Problems solved by technology

This spanning method is a combination of mechanical and electronic control. The spanning wheel, spanning motor and controller form a set of guide wheel devices. The spanning wheel needs to be driven by the spanning motor through a long pole, which requires high flexibility and complex structure. , requires a separate spanning motor and controller to control the spanning wheel, and the software control is complex, so the guide wheel device using this spanning method and the cleaning robot using the guide wheel device are high in cost and complex in design
